How exactly do they "see how we treat dogs"? I must admit I don't see a "reasonable" hypothesis at all.

> Selective quoting,

Yes - because that statement does not make sense regardless of context, so I didn't quote the rest. It also saves space. I always only quote the part that I respond to, the rest of the context always still is right there in an Internet forum, unless OP deletes the post. If I quoted in a different place, for example I quote someone in my own blog post, copying from another website, then I would have to provide the context.
